X + y = 19
10x + 4y = 100
This is a systems of equations.
Isolate x from the first equation:
x = 19 - y
Now, plug it into the second:
10(19 - y) + 4y = 100
190 - 10y + 4y = 100
-6y + 190 = 100
-6y = -90
y = 15
Plug y in and solve for x:
10x + 4(15) = 100
10x + 60 = 100
10x = 40
x = 4
There are four 10-point questions and fifteen 4-point questions.
You can use the formula 2(a+b

This will get you 161.5 ft

It's most likely the first or 3rd answer. Apologies If I'm wrong.
Area= L x W and if the L is 5 yds more than the width is the equation with be...
Area(104)=Wx(W+5)
so 104=W^2+5w
w^2+5W-104 using the quadratic formula you end up getting
W=8
L=8+5=13
13*8=104
Answer:
55%
Step-by-step explanation:
probability of something happening = p
probability of that thing not happening = 1 - P
45%= 45/100= 0.45
therefore, the probability of snow today = 0.45
therefore,
probability there will be no snow=1 - 0.45 = 0.55
probability there will be no snow= 0.55
convert 0.55 back to percentage= 0.55×100= 55%
probability there will be no snow= 55%
